Running REMIND and MAgPIE in coupled mode

David Klein (dklein@pik-potsdam.de) 16 February, 2020

Clone the models

git clone https://github.com/magpiemodel/magpie.git
git clone https://github.com/remindmodel/remind.git

Switch to relevant branchs

For both models switch to the git branches you want to use for your runs, for example the develop branch

git checkout develop

Create snapshot of R libraries

Coupled runs may take a bit longer. During the runtime some of the R packages that are used by the coupled runs might get updated. Updates might change the behaviour of functions in an unexpected way. To avoid this create a snapshot of the R libraries before starting the runs:

bash /p/projects/rd3mod/R/libraries/Scripts/create_snapshot_with_day.sh

Activate snapshot for REMIND and MAgPIE

Direct the models to the snapshot you just created above by editing .Rprofile in the model's main folder respectively. Uncomment these lines:

# snapshot <- "/p/projects/rd3mod/R/libraries/snapshots/2019_02_26"
# if(file.exists(snapshot)) {
# cat("Set libPaths to",snapshot,"\n")
# .libPaths(snapshot)
# }

and change the date to today.

Configure start_bundle_coupled.R

See comments in the head section of the file. Most importantly you need to provide the path to MAgPIE.

Configure the scenario_config_coupled.csv of your choice

By default these are (A) scenario_config_coupled_SSPSDP.csv and (B) scenario_config_SSPSDP.csv. A provides some extra information for coupled runs (e.g. which run should be started). All other settings are taken from B. Thus every scenario in A must also be present in B.

Use the latest GAMS version

This step is optional. If you want to use the latest GAMS version type this into the same command line you will start the runs from:

module load gams/30.2.0

Perform test start before actually submitting runs

Rscript start_bundle_coupled.R test

After checking that coupling scripts finds all gdxes and mifs start runs

Rscript start_bundle_coupled.R
